Loveren’s Mill Atlantic Cedar Swamp

I’d heard about a very special place in Antrim, New Hampshire, a town that lies about 20 miles northwest of Keene. The place is called Loveren’s Mill, named after Josiah Loveren, who in 1864 became the third owner of a combined saw and grist mill originally built in 1798. The mill changed hands several times until it finally closed in 1920. It isn’t the mill site that I went to see however-there is an Atlantic cedar swamp on the property that pollen tests have shown is at least 4000 years old, and most likely much older.

The Atlantic white cedars (Chamaecyparis thyoides) here aren’t cedars at all-they are white cypress-but they are also very rare and appear in just a few pockets along the Atlantic coast. One reason they are so rare is because they grow so slowly, in some cases taking hundreds of years to reach a foot in height.

 

I don’t know if this old stone foundation was for a mill, house, or barn but it sits close to the north branch of the Contoocook River.

 

The Contoocook river is notable as the only river in New Hampshire to run north instead of south. This photo was taken near the site of the mill, which stood a little way upriver on its far side.

 

 As you move away from the river deeper into the woods you can feel that this is an ancient place. Every stump, boulder and log is a garden, covered with mosses, liverworts, ferns, lichens and fungi.

 Before too long, off the main trial to the right, a 200 foot long boardwalk leads through the spongy peat mosses into a grove of cedars.  Atlantic white cedar swamps are rare in New Hampshire and are considered globally rare as well. This swamp is unusual because of its 1,083 foot elevation and by the way the surrounding hills funnel cold air down into it. Because it stays so cool it supports plant life that is usually found only in boreal forests much farther north. I’ve heard that in spring the trails are lined with pink ladies slippers and native pink azaleas. I wouldn’t be surprised to see a great variety of orchids here, along with sundews, pitcher, and other plants that like cool, acidic water.

 

You don’t want to step off the boardwalk because you would probably sink into the floating mat of mosses up to your knees if you did-the trees in this photo are growing in standing water. They can’t stand much fluctuation in the water level, and their survival here shows that things haven’t changed much over the millennia. Still, I have heard that the boardwalks are sometimes under water in spring from snow melt, so it must fluctuate some.

 

Fruiting cones show that the cedars which are actually cypress must be happy. The flat, scaly leaves and grayish, peeling bark are common to both cedar and cypress, so it is easy to confuse the two. Though many cypress are deciduous, these Chamaecyparis thyoides are evergreen, which makes identification even more difficult.

 

Eastern larch (Larix laricina) is another tree that prefers wet, swampy ground and they do quite well here in the swamp. They like to be cool and can stand temperatures down to -85 degrees F. Other trees found here include balsam fir (Abies balsamea) and red spruce (Picea rubens) and like the cypress, these trees are usually found much farther north in boreal forests.

 

There were so many different mosses growing here that I might have to do a post on just mosses. This beautiful thing is one of the fern mosses called delicate fern moss (Thuidium delicatulum). It is very lacy and fragile looking and I don’t see it too often. This moss forms large mats and will grow in sun or shade as long as the soil is moist. It is available commercially for moss gardens.

 

I saw many lichens in the area, but I didn’t expect to see this dog lichen (Peltigera) growing on a moss covered stump. I should have gotten a few photos of its underside-that would have made species identification easier. I’ve never seen it before so I’ll have to re-visit it to be sure about its identity. It grows right beside the trail so it shouldn’t be too hard to find again.

 

This is one of the fruiting bodies (apothecia) of the dog lichen in the previous photo. I’ve heard three different stories of why this is called “dog” lichen. One says that the lichen itself is shaped like a dog. Another says spiky projections on the lichens look like dog teeth, and the third says that the apothecia curl into a shape that resembles a dog’s ear, which you can see happening in this photo.

 

These greenish white growths were the size of toothpicks. I found them growing on a debarked log and as it turned out that is an important identifying characteristic. At least, I’ve identified them as much as I’m able to. Depending on whom you ask these growths are either fungi or lichens.  One web site says they are lichenized fungi, so I’ve decide to go with that. Their name is Multiclavula mucida, and the mucid part of the scientific name means slimy. That’s also important, because these lichenized fungi always grow in association with green algae and the algae is what makes the log in the photo look so slimy. I’ve never seen these before.

 

Something else I’ve never seen is the evergreen creeping snowberry (Gaultheria hispidula). With no flowers it was hard to identify, but I’m fairly certain that the small trailing plant with alternate leaves in the above photo is it. This plant is classified as a prostrate shrub in the same family as American wintergreen (Gaultheria procumbens), which is commonly called teaberry or checkerberry. It has greenish white flowers in spring which are followed by round white berries that are twice the size of the leaves. The berries are said to taste like wintergreen and the crushed leaves smell like wintergreen. This plant is also called Moxie Plum because it is thought to have been an ingredient in the original Moxie soft drink, along with gentian root. Native Americans had many uses for this plant.

 

These small white leptonia  (Alboleptonia sericella) mushrooms were very small and hard to photograph. The largest one is about the same diameter as a pea. I can’t think of anything to compare the smallest one to, but it was tiny. These mushrooms have pink spores and some mushrooms in this family are a beautiful midnight blue.

 

There were many places where the river widened into pools that would be nice to sit beside for a while, but I didn’t have the time this day. That doesn’t bother me because I know I’ll be coming back in the spring. On just a short 3 mile hike I saw 6 or 7 plants that I’ve never seen before, and that amazes me enough to make re-visiting this place a top priority for next season. I get excited just thinking about what plants I might see from spring through summer in this fascinating place.
